--*
--
-- OBJECTIVE:
-- Check that Ada.Text_IO.Editing.Put and Ada.Strings.Fixed.Move
-- have the same effect in putting edited output results into string
-- variables.
--
-- TEST DESCRIPTION:
-- This test is structured using tables of data, consisting of
-- numerical values, picture strings, and expected image
-- result strings. These data tables are found in package FXF3A00.
--
-- The operation of the two above subprograms are examined twice, first
-- with the output of an edited output string to a receiving string
-- object of equal size, the other to a receiving string object of
-- larger size, where justification and padding are considered.
-- The procedure Editing.Put will place an edited output string into
-- a larger receiving string with right justification and blank fill.
-- Procedure Move has parameter control of justification and fill, and
-- in this test will mirror Put by specifying right justification and
-- blank fill.
--
-- In the cases where the edited output string is of shorter length
-- than the receiving string object, a blank-filled constant string
-- will be catenated to the front of the expected edited output string
-- for comparison with the receiving string object, enabling direct
-- string comparison for result verification.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- FXF3A00.A (foundation code)
-- => CXF3A07.A
--
--
-- CHANGE HISTORY:
-- 30 JAN 95 SAIC Initial prerelease version.
-- 11 MAR 97 PWB.CTA Fixed string lengths
